[PATCH AUTOSEL 6.1 18/26] ARM: dts: Fix erroneous ADS touchscreen polarities

Sasha Levin

From: Linus Walleij <linus.walleij@linaro.org>

[ Upstream commit 4a672d500bfd6bb87092c33d5a2572c3d0a1cf83 ]

Several device tree files get the polarity of the pendown-gpios
wrong: this signal is active low. Fix up all incorrect flags, so
that operating systems can rely on the flag being correctly set.
